Hii,
Presently , i am using a property in propertygrid of type Image class to add an image to picturebox at runtime .It is showing the image . No
Problem .
Now , i am not able to get the selected image path as string . I have to save the image path, but it is returning
If Not CType(ctr, PictureBox).Image Is Nothing Then<br />
Dim filePath As String = CType(ctr, PictureBox).Image.ToString()<br />
as "System.Drawing.Bitmap"
if i use imagelocation it is returning as null exception. ' i dont want to use this one
Here, i want to get like this "C:\Documents and Settings\sriram\My Documents\My Pictures\cp.Jpg"
Thanks ,
DVS

Hello,
You can use the ImageLocation property to retrieve the image path. However, you will have to
use the load() method of the Picture box to get the image in the box.
Lets say you have one picture box and two buttons. First button is used to browse for images and
second button is used to retrieve the image path. In this case, you can try the following code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
<br />
Dim ofd As New OpenFileDialog<br />
ofd.Filter = "JPG|*.jpg|BMP|*.BMP|All Files|*.*"<br />
<br />
Dim result As DialogResult<br />
result = ofd.ShowDialog<br />
<br />
If result = Windows.Forms.DialogResult.OK Then<br />
<br />
Me.PictureBox1.Load(ofd.FileName)<br />
<br />
End If<br />
<br />
End Sub<br />
<br />
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click<br />
<br />
MsgBox(Me.PictureBox1.ImageLocation)<br />
<br />
<br />
End Sub
I hope this will help. If you have any doubts, please reply to this thread.

Well Thanks For the reply ,
I dont want in this way . I want in a way like if we select an image property of image type in propertygrid ,then we can select an image at any location and if we click button ok , the image wil be loaded in to the picturebox .In propertygrid it is showing as "System.drawimg.bitmap" without showing the image path .
Or in any way i want the file path . Actually i didnt find any method to get the selected image path in VS2005 or 2003 .Like the one in File Dialog ("FileName")
I want here the file path .
I Really needed it

No, there is no Label.PerformRead().

Although your question does invite ridicule, there is a way to do what you want.
1. Put the code that you want to run when you click the label in a separate sub.
2. call that sub in the click event of your label.
3. also call that sub in the VisibleChanged event of your label:
<br />
Private Sub Label1_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.VisibleChanged<br />
If Label1.Visible = True Then YourSub()<br />
End Sub
4. where you would have called label1.performclick (if it existed, which it doesn't), instead use:
<br />
Label1.Visible = false<br />
Label1.Visible = True<br />
A complete example:
<br />
Private Sub Label1_textChange()<br />
Label1.Text += "bla"<br />
End Sub<br />
<br />
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click<br />
Label1.Visible = False<br />
Label1.Visible = True<br />
End Sub<br />
<br />
Private Sub Label1_VisibleChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles Label1.VisibleChanged<br />
If Label1.Visible = True Then Label1_textChange()<br />
End Sub<br />
P.S. the VisibleChanged event will also fire when your form loads, so you may want to clear it in the Form's Load event:
<br />
Private Sub YourForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
Label1.Text = ""<br />
End Sub<br />
Good luck,
Johan
My advice is free, and you may get what you paid for.

This is a waste of time, txtusername.text.trim is already a string
Vuyiswa wrote: Dim frmmain As New frmmain
This is your new 'main' form
Vuyiswa wrote: Dim frmlogin As New frmLogin
and this is a new 'login' form
Vuyiswa wrote: frmlogin.Close() frmmain.Show()
I'm not sure why showing a main form modelessly, which then immediately goes out of scope, works. But, creating a new login form and then closing it, will do nothing for the other login instance that is already visible elsewhere.
The use of CStr makes me think you've used VB6. You should avoid VB6 constructs, they are nasty, and you should buy a book on OO to help you learn your way past these sort of issues.

Hi all,
I would like to enquire you guys about back and forward buttons (history) like what we have in internet explorers. You could never predict where the user's went previously, etc.. Does anyone know how to go about doing that (code-wise) or have any resource on the net that would be useful(I tried searching - they are all on previous entries instead of previous page)?
Any help would be appreciated. Thanks.

you want back and forward buttons in your windows app, but you think you can't know where the user was before ? Perhaps you need to explain better ?

Yes, ok I mean
here is an example:
I'm currently doing a contract and supplier system. So a user could move from one form to another a lot. Let's say for example I moved from vendor create form, to vendor view then to contract create. NOTE: so, now I'm at contract create form. I have two buttons (named button1 and button2), text are "<<" and ">>", now I want to be able to go to vendor view form when i clicked on the "<<" button.
I hope I managed to explain my doubt. Pardon for any vague explanation earlier on
Any help would be appreciated. Thanks.

anthony
you will get those Errors till you learn that vb6 its Crap, Microsoft is no longer Supporting it. Developers who are still with vb6, they should learn to move on, including you anthony, what benefits do you get in vb6, that you will never get in vb.net ?
move on Brother
